Abstract
When a color image is input, a histogram is generated for each primary color, and a luminance value having the highest frequency is obtained. Next, a luminance value that will become a background candidate is decided in the neighborhood of the luminance value having the highest frequency for each primary color. A value equal to or larger than the decided luminance value is defined to be a background candidate. Additionally, a background color is decided within a background candidate luminance area. By replacing the pixels within the background candidate luminance area with the decided background color, a reverse-side visible portion is removed while maintaining the appearance of the background.
Claims32
An image production controlling device removing a reverse-side visible portion of input image data, and outputting the image data, comprising:
- a histogram generating unit generating from image data a luminance value histogram for at least one color;
- a most frequent value deciding unit deciding a luminance value having a highest frequency from the histogram;
- and
- a background candidate luminance area deciding unit deciding an area in the histogram, having a luminance value which will become a background candidate in a neighborhood of the luminance value having the highest frequency.
An image producing device removing a reverse-side visibility portion of input image data, and outputting the image data, comprising:
- an image data capturing unit capturing image data;
- a first storing unit storing the captured image data;
- a histogram generating unit generating a luminance value histogram for at least one color from the image data stored in said first storing unit;
- a most frequent value deciding unit deciding a luminance value having a highest frequency from the histogram;
- and
- a background candidate luminance area deciding unit deciding an area in the histogram, having a luminance value which will become a background candidate in a neighborhood of the luminance value having the highest frequency.
An image production controlling method removing a reverse-side visible portion of input image data, and outputting the image data, comprising:
- generating from image data a luminance value histogram for at least one color;
- deciding a luminance value having a highest frequency from the histogram;
- and
- deciding an area in the histogram, having a luminance value which will become a background candidate in a neighborhood of the luminance value having the highest frequency.
A computer-readable storage medium on which is recorded a program for causing a computer to execute a process removing a reverse-side visible portion of input image data, and outputting the image data, said process comprising:
- generating from image data a luminance value histogram for at least one color;
- deciding a luminance value having a highest frequency from the histogram;
- and
- deciding an area in the histogram, having a luminance value which will become a background candidate in a neighborhood of the luminance value having the highest frequency.
